Apparatus for canceling noise from broadcast signal for electric vehicle

An active noise removal apparatus comprising:

• a data reception unit configured to receive a bitstream from a transmission device;
• a deinterleaver configured to deinterleave the bitstream to generate deinterleaved data;
• a decoder configured to decode the deinterleaved data to generate decoded data;
• an error check unit configured to check whether an error is detected in the decoded data;
• an encoder configured to encode the decoded data to generate encoded data and then transmit the generated encoded data to the decoder when an error is detected in the decoded data;
• an interleaver configured to interleave the encoded data to generate interleaved data;
• a weight-based channel status determination unit configured to apply a weight for a channel status to the interleaved data to generate weight-based channel status determination information and transmit the generated weight-based channel status determination information to the decoder;
• wherein the decoder includes:
• a first decoder that decodes the deinterleaved data to generate first decoded data;
• a second decoder that decodes the weight-based channel status determination information to generate second decoded data;
• and
• a third decoder that decodes at least one of the first decoded data and the second decoded data to generate third decoded data.
